PacSci-Doku: “Saving The Salmon”

By Dennis Schatz – Senior Advisor

Do you Sudoku? It’s one of the hottest number games around! Well, here’s a twist we think you’ll love. We call it PacSci-Doku. Can you guess why? Here’s how it works. Instead of filling in the blanks with numbers, we use letters. Hidden in one of the columns or rows is the answer to a science question. You’ll find information about the answer on the answer tab below.

The question in this edition is:

What will be a key ingredient in saving salmon from the effects of climate change?

To find the answer, complete this PacSci-Doku using the following nine letters:

The question in this edition is:

What will be a key ingredient in saving salmon from the effects of climate change?

The answer: Cold Water

The lack of snowpack from last winter and last summer’s warm weather caused the streams in the Northwest to be a higher temperature than usual. Salmon, being cold water fish, don’t do well at high temperatures, so died in large numbers as they tried to swim upstream to spawn. Scientists consider this a sample of the challenges to be faced as global warming changes our climate. NOAA (National Oceanographic and Atmospheric Administration) and state scientists in Oregon and Washington are now developing plans to infuse cold water at strategic times from upstream reservoirs to increase the temperature of the streams. Earlier this year, The Seattle Times featured an article outlining NOAA’s plans to deal with our changing climate.
